Our heavy duty, industrial grade BiG400 Shelf Trolley is purpose designed for warehouse, workshop and factory use but is also commonly used in garages, storerooms and picking areas. With a load capacity of 300kg SWL*, the Trolley features strong C-section beams, high-density chipboard shelves with steel central supports and twin-tyre, heavy-duty castors. Finished in powder-coated blue and high visibility orange, the profiled beams simply tap together to create a strong, robust Shelf Trolley suitable for both intensive commercial use and industrial-weight loads.

The base and castors of the Trolley are bolted to the base to maximise its strength and mobility. Four 15mm thick chipboard shelves sit on top of the beams and flush inside the protecting steel uprights. This enhances the rigidity of the framework and gives the Trolley a neat, snag-free finish.

Using the simple assembly principles of the boltless, stud-and keyhole design, the fully modular construction of the BiG400 means that that it can be easily adapted to the products and, with the benefit of heavy-duty castors, the working locations too.

A flexible and easily adaptable, heavy-duty shelving trolley for warehouse and industrial use

Relatively easy to assemble - about 30-40 minutes with a cordless driver and sockets (15mm, 13mm & 10mm - but one of the 10mm nuts is very tight and will need a 1/4" drive socket). Rubber mallet also useful if not essential. The main 'beams' to 'castor bracket' could really do with some means of auto-squaring as the bolt hole tolerances make it a bit sloppy and make it difficult to tighten the 15mm nuts easily *and* keep everything square. I would suggest all the shelves need 2 middle supports. Some screw holes in the beams would be useful to secure shelves to and would improve the rigidity/strength. I will be very surprised if the castors can take a tonne between them but I may be about to find out! Not quite sure why the colours have to be so garish!

I bought 3 mobile shelving units and a mobile bench. Great build quality. You need more than a mallet as there are loads of nuts and bolts so it took me 2 days to do all 4 items. However the addition of the castors and bolt heads means these trolleys are longer by 2-3 cm. Annoying for me as I had a specific location for 2 of them and I can't get them in. Catalogue needs to be corrected.

Once assembled, these shelves are really good - I went for the trolley wheeled version so I could move it around and that is already proving to be a wise move in my circumstances.

My only gripe is with the instructions - a tiny slip of paper with hardly any guidance on it meant that I wasted a fair bit of time undoing bolts to re do them in the correct places. If I was doing another one today, it would be much easier ofcourse, but for the first one, it would helpful to have more explanation of which bolt size goes in which bit as there were three different sizes and only certain ones fit in certain parts. I also was left with some parts that don't seem to have a purpose and were not mentioned in the instructions. I don't know if they were meant for a different sized product, for joining multiple shelves together, or I've missed something out... again, clearer instructions would have helped.

That aside, once assembled correctly the product is great and I would have no hesitation getting more in future. BigDug service is also excellent - delivery was quick and communication was good.
